Specification of Letters Patent.

Application filed December 28, 1917. Serial No. 209,272.

ends to backs 19 Carried by the hun 1o While e To aZZ'wwm 'it mayconcern Be it known that I, JOHN Toroznwsnr, a citizen of Russia',residing at Chicago, in the county of Cook and State lof Illinois, haveinvented certain new and useful Improvements ,in Ship-Protectors, ofwhich the following is a specification.

The primary object of the invention is the provision of a protector forships adapted for mounting upon the hull thereof for presenting a spikedbarrier to the enemy as well as resilient holding means for torpedoesand thereby preventing injury to the ship.

A further object of the device is the provision of a torpedo catchingplate foldably carried by the hull of a boat and resiliently mountedwhereby upon being struck by a torpedo, the force of the blow will becushioned and the torpedo will be held by its sides in a suspendedmanner without exploding the torpedo and saving the ship uninjured.

A still further object of the invention is the provision of aresiliently mounted barrier foldingly carried by the hull of a shiparranged with spaced resilient members adapted for catching and holdingtorpedoes before reaching the hull.

In the drawings forming a part of this application and in which likedesignating characters refer to corresponding parts throughout theseveral views,

Figure 1 is a side elevation of a ship provided with my device.

Fig. 2 is a top plan view thereof.

Fig. 3 is an enlarged elevational view of a portion of the structure.

' Fig. 4 is a side view thereof with parts broken away,

Fig. 5 is a detail sectional view taken upon line V-V of Fig. 4, and

Fig. 6 is a sectional View taken upon line VI-VI of Fig. 4.

Referring more in detail to the drawings, my device is hereinillustrated in connection with the hull 10 of a ship 11 having a cabin12, funnels 13, and wireless apparatus 14.

The device broadly consists of a plurality of frames or ygrids 15foldably carried by the hull 10 upon hinged arms 16 while the grid isarranged with openings l17 through which an oncoming torpedo may projectand become engaged with catching members 18 arranged at each corner ofthe said openings 17.

The arms 16 are pivoted at their inner hinged collars 20 are hinged asat 21 to the grid 15 and with the vcollar portions 22 slidably arrangedupon the arms 16. Springs 23 interposed between the collars 22 andshoulders 24 of the arms adjacent their inner pivoted ends serve toresiliently hold outwardly the grid 15 which is connected to the collars22, itbeing understood that heads 25 are formed on the outer ends oflthe arms Patented Apr. 1e, 191s.

16 to prevent the collars 22 from being ref moved from the arms, saidheads 25 being normally arranged in circular openings 26 in the oppositesidesof the grid. -The grids 15 are connected together by links 27 andare maintained unfolded by cables 28 attached to the terminal grids 15and passing through the sides of the hull 10, it being understood thatthe grids may be swung to-y ward the stern 29 of the hull in theirfolded positions vagainst the hull whenever desired and may be againunfolded to their outwardly arranged protecting position by means of thecables 28 whenever desired for use.

. Spikes or spears 30 are carried by the grids 15 intermediate thecatching members 18 so that the outer faces of the grids present theappearance of a formidable barrier when approaching the ship from eitherside thereof. Any oncoming object may hit the spears 30 or any portion`of the. grid 15 and the impact of the blow will be cushioned by means ofthe springs 23. The catching members 18 each consist of a lug 31 havingfour resiliently mounted ears 32 thereon normally positioned insubstantially the Vform of a pyramid with the point outwardly arranged.A torpedo approaching the hull 10 become engaged with the catch members18 as well as the adjacent portions of the grid 15 while the cushionedsprings 23 and the resiliency of the catching members 18 stops themovement of the torpedoV and holds the same in the water withoutstriking the hull 11.

The device presents only little resistance to the passage of the shipthrough the water as the grids 15 are folded flatly against the hull 10when not in use while in the manner indicated, the device prevents anyinjury to a ship which is provided therewith.

1. A ship protector com rising a grid, hinge means adapted for oldablymounting the grid upon a hull7 cushioning means for the grid carried bysaid hinge means, and resilient torpedo catchingl members' upon theouter face of the grid.

2. A protector for ships hulls comprising arms pivotally mounted uponthe hull,

vhinge collars resiliently carried by said arms, a grid pivoted to'saidcollarsvadapted for fiatly engaging the hull when the device is foldedand for arrangement outwardly and in parallelism therewith whenoperatively arraI-igcd and resilient torpedo catching meansv carried bythe grid.

3. A protector for ships hulls comprising arms pivotally mounted uponthe hull, hinge collars resiliently carried. by said arms, a gridpivoted to said collarsadapted for flatly' engaging'. the-hull when thedevice is folded and for arrangement outwardly and in parallelismtherewith when operatively arrangech. sai-dy gridl arrangedY withtorpedo receivii'igopenings therethrough, outwardly projecting lugscarried. by the grid at the corners of said openings,- sets ofresiliently mounted ears up'on said lugslnorlnally positioned in anoutwardly pointed arrangement, and outwardly projecting. supportscarriedby the grid intermediate the said lu s.-v

;gi'. A device of the class described comentamos-ime mammary be attainedfor prising a grid having perforations in the side rails thereof,mounting arms arranged with heads positioned within said perforationsand having shoulders adjacent their opposite ends, pivoting blocks forthe arms at the shouldered ends of the arms, hinge collars piv-oted tothe grid adjacent said perforations with portions slidably arrangedaround said arms, and cushioning springs upon the arms between saidcollars and shoulders.

5. A device of the class described comprising a grid having perforationsin the side rails thereof, mounting arms arranged with heads positionedwithin said perforations and having shoulders adjacent their oppositeends, pivoting blocks for the arms at the shouldered ends of the arms,hinge collars pivoted to the grid adjacent said perforations withportions slidably arranged around said arms,.cushi0ning springs upon thearms between said collars and shoulders, sets of resiliently mountedcars carried by the grid adjacent the openings therein at lthe oppositeside ot' the grid from said arms and outwardly projecting spears carriedby the grid.

In testimony whereof I aiiX my'signature.
